The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2018:0163 advisory.

    389 Directory Server is an LDAP version 3 (LDAPv3) compliant server. The base packages include the     Lightweight Directory Access Protocol (LDAP) server and command-line utilities for server administration.

    Security Fix(es):

    * A stack buffer overflow flaw was found in the way 389-ds-base handled certain LDAP search filters. A     remote, unauthenticated attacker could potentially use this flaw to make ns-slapd crash via a specially     crafted LDAP request, thus resulting in denial of service. (CVE-2017-15134)

    Bug Fix(es):

    * Previously, when a connection received a high operation rate, Directory Server stopped to poll the     connection in certain situations. As a consequence, new requests on the connection were not detected and     processed. With this update, Directory Server correctly decides whether a connection has to be polled. As     a result, connections with a high request rate no longer remain unprocessed. (BZ#1523505)

    * Previously, if Directory Server was stopped during an operation which created additional changes in the     memory changelog, the Replication Update Vector (RUV) in the changelog was higher than the RUV in the     database. As a consequence, Directory Server recreated the changelog when the server started. With this     update, the server now writes the highest RUV to the changelog only if there is the highest Change     Sequence Number (CSN) present in it. As a result, the database and the changelog RUV are consistent and     the server does not need recreating the changelog at start up. (BZ#1523507)

    * Due to a bug, using a large number of Class of Service (CoS) templates in Directory Server increased the     virtual attribute processing time. This update improves the structure of the CoS storage. As a result,     using a large number of CoS templates no longer increases the virtual attribute processing time.
